Abstract: A memory device includes a plurality of memory cell transistors, a first word line, a controller, and a storage circuit. Each of the plurality of memory cell transistors stores a plurality of pieces of bit data. The first word line is connected to a plurality of first memory cell transistors in the plurality of memory cell transistors. The controller performs a loop process including repetition of a program loop including a program operation and a first verification operation. The storage circuit stores status information. The controller performs the loop process, then performs a second verification operation, and stores first status data corresponding to a result of the loop process and second status data corresponding to a result of the second verification operation in the storage circuit, in a write operation using the plurality of first memory cell transistors as targets.

Abstract: In a mobile communication network system for locking an operation on a cellular telephone comprised of a cellular telephone body, and an information storage medium that is inserted in the cellular telephone body and that is assigned a specific telephone number, provided are a service control apparatus that associates a terminal identification number assigned to the cellular telephone with the telephone number of the information storage medium currently inserted in the cellular telephone to manage, and an information management server which acquires a telephone number of the information storage medium corresponding to the terminal identification number of the cellular telephone targeted for locking from the service control apparatus, and locks the operation on the cellular telephone based on the telephone number.

Abstract: With stereophonic sound images of multi-channel audio signals well maintained, 2-channel system audio signals are created. An acoustic image creation system includes: a left-rear localization processing means 2 for outputting a left-rear localization signal by summing together a left signal 101 and a left-rear signal 103, among audio input signals including the left signal 101, a right signal 102, the left-rear signal 103, and a right-rear signal 104, and processing the summation result with a rear localization processing filter; a right-rear localization processing means 3 for outputting a right-rear localization signal by summing together the right signal 102 and the right-rear signal 104, and processing the summation result with a rear localization processing filter; and an acoustic image creation means 4 for creating the surround sound image signals from the left signal 101, the right signal 102, the left-rear localization signal 103, and the right-rear localization signal 104.

Abstract: The present invention provides a method effective for diagnosis or treatment of congenital disorders of glycosylation syndrome (CDGS) by clarifying the gene of the N-linked sugar chain synthase in human endoplasmic reticulum. In the present invention, a gene of an enzyme catalyzing human N-linked sugar chain synthesis is found based on, as indicators, whether it is homologous with the gene of the enzyme catalyzing N-linked sugar chain synthesis in yeast endoplasmic reticulum and compliments the function of the gene for a deletion yeast strain of the gene.

Abstract: A counter increments a count value every given time period. An adaptive operation control unit selects channels in which adaptive operations are done from all the channels in obedience to the count value to output produced selection signals to AND circuits. Double-talk detection circuits judge the presence/absence of a double-talk state and output detection signals to the AND circuits. The AND circuits operate logical AND of the selection signals and the detection signals and output the logical AND results as control signals to filter coefficient updating circuits. The filter coefficient updating circuits update or do not update filter coefficients stored in FIR filter units according to the control signals. The FIR filter units produce echo replicas by calculating convolutions of the filter coefficients and the receive signals. Subtractors subtract the echo replicas from transmission signals to output residual signals.

Abstract: By screening an animal cell transformant, which has been obtained by introducing into wild-type animal cells a wild-type DHFR gene and a structural gene which codes a desired useful substance, with a medium containing methotrexate (MTX) at a concentration of 50 .mu.M or lower, both genes can be amplified effectively within an MTX resistant strain and a stable amplified transformant can also be obtained. The screening may be repeated using an increasing concentration of MTX. It is also possible to obtain stably the desired foreign gene product in a high yield by using the thus-obtained amplified transformant.
